Swiss scientists at Federal Institute of Technology in Lausanne have demonstrated a robot that can be controlled through human mind, made for immobile patients.
A quadriplegic person wore a cap to transmit signals from his brain successfully to this special robot which could move left or right, simply based on thinking. It will aid paralyzed patients to view the happenings around them otherwise impossible while sitting idly on a wheelchair.
One core issue that hinders in the practical implementation of this technology is that once human brain loses the concentration for even for a second the transmission of signals can degrade. So, an undeterred and continuous flow of thoughts is required for smooth sailing.
Researchers are hoping to cope this shortcoming and out a commercial robot in few years time only.
